The next idea I would like to share is a new one that I recently learned about over the summer while completing training for a math group I joined in my school district called Math Rocks. The website is called “Which One Doesn’t Belong?” The basic idea is to share a picture with your students and discuss which picture or element of the picture does not belong. Here’s the beauty of it: There is no right or wrong answer. As long as students can justify their response, their answer is correct. Here are some ways you can use this in your classroom:
- Display a picture. Have students determine which one doesn’t belong. Designate a corner of the room for each picture. Ask students to go to the corner of the room that represents which picture/ element they believe doesn’t belong. Once students meet-up in their chosen corners, students discuss their reasoning for why their picture doesn’t belong. Then have the groups share-out.
- Display the picture. Challenge individuals or small groups to determine why each picture could be the one that doesn’t belong. As a class, share your reasoning.
- Display the picture. Designate a corner of the room for each picture. Randomly select students to go to each corner. Then ask students to go to their assigned corner. Once students meet-up, have them determine a reason why their picture does not belong.
- Have students determine a picture to add that would complete the set (depending on their “rule” for the set.).
- Have students determine an object that would not complete the set (depending on their “rule” for the set.)
- Have students create their own “Which One Doesn’t Belong?” picture. Use the pictures throughout the year to challenge your students.
